' A nmau filed October 5, 1901'. Serial no. 77,677. (No model.)

To all whom it may concern:

Be it known that we, JAMES ROXBURGI-I, manager of printing-works,residing at 10 vented certain new and useful Improvements in Apparatusfor Slotting Linotype-Slugs, of which the following is a specification.

This invention relates to the utilization of linotype-slugs or lines oftype for printing tabular work, and has for its object to facilitate andexpedite the formation of transverse slots in the slugs or lines of typefor receiving the metal rules or strips for printing the lines betweenadjacent columns of the tabular 'work and to feed the forms or framescontaining the linotype-slugs or lines of type regularly and easily tothe aforesaid means for forming the transverse slots in the slugs orlines of type.

According to our invention we mount a number or series of circular sawsadjustably on a rotary shaft or spindle carried by a sawtable,spacing-disks or type-measures of any required typographical width beingalso mounted on said spindle in intermediate positions between the sawsand arranged so as to adjust the spaces between the saws in accordancewith the required spaces between the columns of'the tabular work.

. The chases or frames in which the slugs.

or lines of type and the rules are imposed or arranged have their sidemembers adapted to engage with fixed guides on the saw-table, wherebythe said slugs are fed regularly and rapidly to the circular saws.

Referring to the drawings, Figure l is an elevation, partly in section,of a saw-table constructe'daccording to this invention. Fig. 2 is a planof said table. Fig. 3 is a plan, and Fig. 4. is an end elevation of achase or frame containing the imposed lines of type and rules. Fig-5shows the spindle detached from the saw-table. Fig. 6 is a side View ofone of the circular saws. Fig. 7 is a side view of a spacing-disk ortype-measure.

a is the saw-table, which carries a spindle b, on which are mounted sawsc c and spac ing-disks or type-measures d d of the requiredtypographical width. The spindle b is mounted in bearings e e, which maybe vertically adjusted by means of screws ff and nuts 9 g, so as toregulate the height of the cutting edges of the saws 0 above the tablea. The spindle bis provided with a key or rib h, Fig. 5, which engageswith. corresponding keyways or grooves 2', Figs. 6 and 7, in the saws cand disks or type-measures d, thereby preventing the said saws and disksfrom moving angularly about the spindle. The saws c and disks (1 areadapted to slide longitudinally on the spindle b and are retained inposition by a nut j, which engages with the screw-threaded end of thespindle.

The saw-table ais provided with undercut guides 70, between which achase or frame 1, having correspondingly beveled or inclined sidemembers 772, is adapted to slide. linotype-slugs or lines of type n,Figs. 3 and 4, are imposed or arranged in said chase or frame, and thechase or frame containing the slugs n is then passed along between theguides 7t, while the spindle bis rotated by any convenient means, suchas the band and pulley gear. (Shown in Fig. .2.) Transverse slots 0,Figs. 3 and 4, are thus cut in the slugs m. In these slots 0 brassstrips or rules 13 are inserted for printing the lines between thecolumns of the tabular printed work.

If required, the chase or frame may besupported by one or morecross-bars, such as s, Fig. 3.

The disks or type-measures vary in width from the lowest or less thanthe lowest up to any recognized or convenient typographical measure. Byarranging disks of the required width between the saws on the spindleany required typographical space can be obtain ed between adjacent saws,and as the saws cut the transversegrooves to receive the rules in theslugs or lines of type it follows that by a suitable arrangement ofspacing-disks and saws upon the spindle-spaces of any requiredtypograpical measure may readily be obtained between adjacent rules.

A type-gage 15 may, if desired, be provided on the saw-table andgraduated in accordance with the usual typographical measures to aid theoperator in arranging the saws c and spacing-disks d on the spindle.

What we claim, and desire to secure by Let ters Patent of the UnitedStates, is-

1. In apparatus for preparing linotypeslugs or similar cast lines oftype for printing tabular matter, the combination of a saw-table, arotary shaft carried by said table, saws for cutting transverse slots inthe slugs, carried by and longitudinally adjustable on said shaft,vertically-adjustable bearings for said shaft to regulate the depth ofthe transverse slots in the slugs, interchangeable spacingdisks of anyrequired typographical measure mounted alternately with the saws on saidshaft in accordance with the spaces required between the columns oftabular matter,guides on the saw-table and a chase or frame having itsside members adapted to engage with said guides, substantially as andfor the purpose specified.

2. In apparatus for preparing linotypeslugs or similar cast lines oftype for printing tabular matter, the combination of a saw-table, arotary shaft carried by said table, saws for cutting transverse slots inthe slugs, carried by and longitudinally adjustable on said shaft,vertically-adjustable bearings for said shaft to regulate the depth ofthe transverse slots in the slugs, interchangeable spacingdisks of anyrequired typographical measure mounted alternately with the saws on saidshaft in accordance with the spaces required between the columns oftabular matter, undercut guides carried by the saw-table and running atright angles beneath the rotary shaft, and a chase or frame havingbeveled side members adapted to engage with said guides, substantiallyas and for the purpose specified.

In testimony whereof we have hereunto set our hands, in presence of twosubscribing witnesses, this 19th day of August, 1901.
